    Finding alien life on a distant planet would be amazing news - or would it? If we are not the only intelligent life in the universe, this probably means our days are numbered and doom is certain.

      Would it not be more helpful and positive to find advanced civilizations who may have already seen the great filter and can help us avoid it?

      our creator gave us a perfect planet to sustain life..MAN continues to destroy it..why bother going to another planet when we havent learned and evolved enough to care for the planet were on now...we can have a great place for future generations if we gave a shit besides money and greed, possibly having any moral integrity..but weve lost our moral compass so unfortunately Armegedon will need to occur

      @Rej Erh Very enlightening. Thanks. Also, i didn't quite understand why it would be so bad if we find out that the filter is behind us. The videos says "finding bacteria would be bad... intelligent life, alarming." referring to the first scenario. i couldn't make the connection. Would you care yo explain this? (i know you're not the owner of the channel, that's why i'm kindly asking ).

            we will never find aliens that look like us, we share the planet with thousands upon thousands of mammals sharing the same conditions, and look at the variation in diversity. do you really think homo sapiens are just gonna pop up on Mars?

              we need to learn how to live without pooping. seriously, we can't go on a trip to Mars and have to poop so much. plus we need too much water, if we could look earn to drink ammonia that would be better.

                100 years ago we were using horse and buggies. Slow your roll. Your theory is shaped around Darwin's with a strange theory that an organism at some point merged with another to create more complex life in all it's variations. Apply ancient astronaut theory to that. Do you really believe resources could be shipped across the galaxy efficiently? If the moon was lined with bars of gold. We would not be able to carry enough back to pay for the trip. I thought they were going to go with the discrediting religion and the breakdown in morality would be our doom. The reason religion was created. So you don't believe aliens have visited us? Then you are a small minority.

                      They just discovered that many solar systems have a Jupiter gas giant where our Jupiter is so that's not it. There probably isn't a great filter though. Our universe is young considering how long it takes for heavy elements to form. Life probably isn't possible until at least the second generation stars form. It probably requires third generation stars. The aliens we are seeing if we are seeing any are the few who made it just a little ways ahead of us and are only now just exploring. (By a little way I mean they could be millions of years ahead of us so hopefully within a thousand years we will achieve warp drives or something similar. With their help perhaps even sooner.

                                    well it depends on how far the planets are. for example a planet is 20 million light years away, if the civilization was sophisticated enough to make a super strong telescope that could see the surface of planets they would see prehistoric giraffes and bears and what not. this is because light is reflected and they would see what is reflected from the distance. therefore we’re probably seeing the planets before life started and that’s why we can’t find aliens near us.

                                      The filter theory is the most depressing and dumbest invention when it comes to evolution. In a fluent progression there's not such a thing like a "step". Its the same like there is no distinct present as everything not ahead of us is already the past - and what doesn't make it any easier is the bending of SPACETIME.

                                                        that is a really good video/arguement but if i understand it correctly, you just took it for a fact that humanity already is able to recognise signs of alien life?
                                                        what if we are still not advanced enought to see what lies ahead of us?

                                                        as you mentioned, we have nothing to compare our inteligence against, other than what we have here on earth. what if, on a universe scale, we are just really really really dumb?

(2:27) It's not like we could just make some high quality photos of any planet in our galaxy, yet alone in another galaxy. We're not able to look closely at asteroids traveling between different planets in solar systems far away, heck we're not even able to look closely at far way planets. So I find the very basic assumption that "we don't see anything, so space seems empty. Why?" to be just naive.

I want to believe that's what's going to happen to us.

The technology is out there to be discovered but humans can't work with each other long enough to figure it out.

It's purely circumstantial and it's very loosely correlated to this potential scenario
